Hi everyone, I've been using the BeagleBone Black for a while now. I got my apps running just fine for like *2-3 months* straight, not a single problem.
OS : Debian Wheezy installed on Samsung 4GB µSD card. Cross compilation platform : ELDK (armv7-hf) I've tested my apps on *different brands of SD Cards* (Kingston, samsung, sandisk ...) and have killed several *Kingston* cards in a matter of days. By killing, I mean the BeagleBone wasn't booting on them anymore and they were no longer mounted when plugged via a USB-Card-reader. I had this kind of dmesg output (the [...] here means a lot of the same 7 lines in a loop): [626903.528266] sd 11:0:0:0: [sdd] Device not ready [626903.528268] sd 11:0:0:0: [sdd] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [626903.528272] sd 11:0:0:0: [sdd] Sense Key : Not Ready [current] [626903.528275] sd 11:0:0:0: [sdd] Add.

Everything was fine for *2-3 whole months*, but now I had one of my systems getting the *exact same symptoms* as when using the Kingston cards. Did anyone experience this kind of problem using his beagle bone so far ? Does anyone have an idea of something that could damage the SD card so much which is or isn't directly related to the use of a beagle bone black (Heat, compulsive logging, ...) ? Can anyone suggest a brand that has solid and enduring SD Cards for an app that is logging quite regularly ?
